Rhabdomyosarcomas (RMSs) are a group of soft-tissue malignant tumours. They derive from primitive skeletal muscle tissue with head and neck as its principle location. These tumours are extremely rare in adults and it is believed to have a different natural course, treatment response, and prognosis. The invasiveness of tumour, metastasis, lymph node involvement, and the age at diagnosis is a predictor of outcome in patients with RMC. Hence early recognition and histological sub-typing is of critical importance in the therapy of the disease. We report a rare case of RMC in a 50-year-old female patient involving the left maxillary alveolus with a detailed clinical, radiological, histopathological and immunohistochemical findings.
